Definitions

  • the invention relates to the transport machine and in particular to shock absorber systems on a suspension. It can be used in front and rear bumpers of automobiles and other engineering
  • the object of the proposed invention is to increase the reliability of a shock absorber and increase the stability and comfort of an automobile when moving under difficult road conditions by a new method of ensuring the regulation of the hydraulic resistance and consequently the hardness of the shock absorber in the working process different road conditions and depending on the load of the automobile.
  • the invention provides in the method of regulation of the hydraulic resistance of the shock absorber in the working process, which includes a forced overflow of the operating fluid through small cross-sections from the chamber without piston rod in the piston rod chamber and back, according to the invention passage cross sections with variable transmissibility, which is achieved by the use of mutually displacing metering elements, the permeability being changed due to the effect of the changes in the difference between the hydraulic pressures in the piston rod chamber and the chamber without piston rod, which arise as the load on the shock absorbers changes.
  • Fig. 1 the overall view of the construction of a shock absorber is shown, with which the pending method can be realized.
  • Fig. 2 will the Construction of an assembly with a regulator shown on an enlarged scale.
  • the shock absorber consists of the piston rod 1, the working cylinder 2, the outer container 3, the upper monoblock 4, which serves as a guide for the piston rod and the seal, from the piston 5, the regulating piston 10, which is cushioned by the spring 14, from the Regulierkolbenstange 11 and from the cylinder 16 with the regulating nut 15th
  • the regulating piston rod 11 is partially disposed within the regulating piston 10 with the clearance h, which forms a small passage cross-section with a variable transmissibility which varies depending on the depth of immersion of the regulating piston rod 11 into the regulating piston 10.
  • the method is realized as follows:
  • the piston 1 of the shock absorber When compressed, the piston 1 of the shock absorber moves down and the eye 19 upwards.
  • the operating fluid moves from the chamber without piston rod 17 in the piston rod chamber 18 by overcoming the small resistance of the disc 7 via the channels 6 in the piston 5.
  • a portion of the operating fluid is forced through the volume of the shock absorber piston rod from the chamber without piston rod through the channels 13 into the outer container 3, thereby compressing the gas 20 located therein.
  • the piston rod 1 of the shock absorber moves upwards and the eye 19 moves downwards.
  • the channels 6 are covered in the piston 5 by the sprung disc 7.
  • the liquid passes through the metering opening 8 in the channel 9 within the piston rod 1 of the shock absorber and reaches the metering piston 10, where it encounters great resistance, passing through the small passage cross section of the game h between the inner walls of the metering piston 10 and the Dosierkolbenstange 11 therethrough occurs, after which they pass through the channels 12 of the cylinder 16 into the piston rod lying chamber 17 exits.
  • a portion of the liquid is displaced by the gas 20 and enters through the channels 13 from the outer container 3 in the piston rod 17 opposite the chamber.
  • the operating fluid above the regulating piston 10 generates a pressure which exceeds the pressure of the spring 14 and there is a displacement of the Regulierkolbens 10 down.
  • the Regulierkolbenstange 11 enters deeper into the Regulierkolben 10, wherein it increases the length of the game between them, and consequently reduces the transmissivity of the passage cross-section. This increases the flow resistance when overflowing the liquid, which increases the resistance of the shock absorber. In this way, the regulation of the hydraulic resistance of the shock absorber is carried out in the working process.
  • the application of the proposed method has the following advantages: No delay in the damping of shock absorbers, the possibility of using softer shock absorbers for high-speed automobiles and maintaining the steerability of an automobile with high loads on the shock absorber.
  • the proposed device can be easily scaffolded in known designs of hydraulic and hydropneumatic shock absorbers in domestic and foreign automobiles.
